Produces very good quality (for lot I received) to a bottom prices

Inks purchased for the price, of course. First good surprise: no Cartridge recognition problem on my HP6180.
I expected an average print quality suitable for text only. But printing photos in maximum resolution on photo paper (cheap too) is just bluffing! The rendering is better than photos taken in a large neighboring surface. Pixelation invisible colors absolutely true, deep blacks ...
The cost per page is very low. As often is the yellow color that will drain quickly since there is a yellow cartridge, unlike the Cyan and Magenta.
The large capacity of these cartridges is an added advantage. I still have not seen the gauge down, and as they are transparent, we have a real view of the level.
As always with low-cost compatible, we can not be sure that the next batch will be as perfect, but 70cts cartridge, I will recommend in a heartbeat.
To parody of an advertisement it a few years ago: it would be crazy to spend more!
A product that I recommend without reservation.
